Mosquito-borne Diseases

Connecticut Mosquitoes

 

Mosquito-borne diseases are those spread by the bite of an infected mosquito. These diseases can be caused by viruses or a parasite. Viruses cause the majority of mosquito-borne diseases, and there are no medications to treat the symptoms caused by these viruses. Some mosquito species found in Connecticut are capable of spreading viruses that can cause disease in humans. Illness associated with these diseases ranges from mild to significant, and some can cause death. In Connecticut, surveillance is conducted to identify travel-related diseases (diseases acquired out of the state or out of the country) and diseases that can be spread by mosquitoes in the state. The Connecticut Department of Public Health conducts surveillance for the following mosquito-borne diseases:

 

California Serogroup viruses (e.g. Jamestown Canyon, LaCrosse)

Chikungunya virus

Dengue

Eastern Equine Encephalitis

Malaria

Saint (St.) Louis Encephalitis

West Nile virus

Yellow fever

Zika virus

 

The most effective way to avoid getting sick from mosquito-borne diseases is to prevent mosquito bites.

Connecticut Mosquito Management Program

 

The Connecticut Mosquito Management Program is a collaborative effort involving the Department of Energy and Environmental Protection, Connecticut Agricultural Experiment Station, Department of Public Health, Department of Agriculture, and the University of Connecticut Department of Pathobiology and Veterinary Science. The program provides information about the species of mosquitoes found in Connecticut and guidance about how to protect yourself and your community from mosquitoes and mosquito-borne diseases.

Connecticut Agricultural Experiment Station

 

The Connecticut Agricultural Experiment Station conducts mosquito trapping across the state during June through October. Mosquitoes are tested for viruses that can cause human disease, including those found in Connecticut such as Eastern Equine Encephalitis virus, Jamestown Canyon virus, and West Nile virus
